IMPROVEMENT, IN STREET-WASHER BOXES.

Specification forming part of Letters Patent No. 156,577, dated November 3, 1874; application tiled January 28, 1874.

tical central section.

This invention relates to an improvement in the box or case which is placed in the earth around the pipe and valve stem, through which water is led from the supply-pipe to the surface, commonly called street-washer boxes. These have usually been made of Wood, fitted to receive theiron cover at the top, and as the depth of the supply-pipe from the surface is variable in different places the boxes must be cut or fitted to the required depth. These boxes soon decay, so as to require frequent renewal.

The object of this invention is to produce a box which will not decay, and be adjustable as to length; and it consists in a box formed from two or more sections of met-al, the upper section constructed to receive the cap or cover, one section fitting into the other so as to be adjustable as to length.

A is the upper section; B, the second section, the two formed, preferably, from sheetiron galvanized or otherwise prepared to prevent oxidation, and so that one will slide into the other, as seen in Fig. 2. The upper section A is constructed at the top to receive the cap C, `which may be of the usual form. When not required for use, or for transportation, the parts may be closed together; then, when required for use, drawn out, as seen in broken lines, Fig. 2, and set into the earth; then the upper section pressed down until the desired level is attained.

This box costs little more than the common wood box, but will ontlast many such, besides possessing the advanta ge ofr ready adjustment.

I claim as my invention- A street-washer box, consisting of two or more sections, A B, made adjustable one within the other, and the upper section constructed to receive the cap, substantially as described.
